hi there,,,

i dont have a honda car,,,

thermostat is sometime stuck and water cannot go flow through,,,

then radiator / motor will getting HOT and steam off,,,

not good idea thermostat in the vehicle,,,

take off thermostat and water keep going flow through that help more cooler water without stuck

@bestamerica yeah right ha ha , maybe in your world, but not here in the desert of Arizona , no frik'n way it's part of a engine necessity . we have triple temp never ending heat here in the summer . if I pulled out the thermostat on my tow vehicle (Suburban 454 7.4 liter big block) the cooling fluid would move To quickly through the radiator and never have a chance to cool down. if "YOU" only drive a mile a day in a Honda , then I can relate to your comment

@lsxtreme

did you ever get your problem fixed?

I currently have a 1995 Toyota Corolla 4 cylinder and I'm having the same problem you are except I can drive my car anywhere where the elevation of the road is flat. But when I start to climb a hill, like beginning to drive over a mountain, my car then starts to over heat and the radiator fluid drops and is pushed out through the overflow tube. A few people have told me that I have a cracked head gasket. What do you think it could be? thanks!

The blown head gasket theory goes out the window --- when you mentioned no "smoking" through your tail pipes; but have you checked your catalytic converter? It's a probability that your catalytic converter is faulty/malfunctioned hence not enabling your engine to "breathe" properly or rather rid itself of high-temperaturized & pressurized gases hence contributing to the overheating of your engine.

calapse?? i've leak down test it, compression test it everything comes fine? but where to look @ now? no smoking through tail pipes, drives. new waterpump, thermostat, rad hoses, new radiator!! what you think.

[lsxtreme]

hows it going! Got a few questions, I'm having alot of issues with my vehicle. It's a 95 acura integra, what it's doing is over heating and loosing coolant! It will not overheat just by letting the car idle. Only while driving! mechanically wise it is running properly. Fan is kicking in, thermostat is opening when it should. replaced all temp sensor/fan switch gauge temp sensor. just to get them out of the questions. but still it would over heat. and next morning the upper/lower hoses would
